This is quite old but it’s the most up to date I could find.
There’s been quite a bit of discussion on this thread about how people do their bit by recycling their waste and how governments need to ban private planes.
I’ve said a few times, that’s all well and good, but it’s a drop in the ocean. Blaming other people for being profligate, while saying that we already know what we have to do, is burying our heads in the sand.
Half of our emissions come from electricity and heat generation and from agriculture, forestry or land use. Only 14% is from transportation, and private jets will be a small fraction of that. So banning private jets is just another drop in the ocean. All the yogurt pots and t-shirts that we are cutting down on are part of the 21% included in Industry, so even if we were to do away with that sector all together, it leaves 80% of emissions to deal with. And we will never do that by recycling our yogurt pots and making our clothes last longer.
If we really want to make a difference, it’s the electricity and heat generation we have to deal with, plus land use. And the only people who can make a big enough difference in those areas are the governments. Everything else is very good and worthwhile, but its tinkering.
Renewable energy and sustainable land use is what we need.
I realise that the figures will have changed in the last decade but it’s the relevant size of the slices which is important.
